SPECIFICATION forming part of Letters Patent No. 447,045, dated February24, 1891.

Application filed May 9, 1890.

To all wwm zit' may concern:

Be it known that I, NOEL B. GINOOHIO, a citizen of the United States,residing at New York, in the county and State of New York,

` have invented certain new and useful Improvements inl\Iagneto-Electric-Signal Devices, of which the following is aspecification.

My invention relatesto magneto-electric Signal devices, and moreespecially to that class adapted to be used in connection with telephoneand telegraph and other signaltransmitting lines, and it has for itsObject to provide an improved device whereby certain prearranged anddistinctive signals can be given at will; and to these ends my inventionconsists in the construction, arrangement, and combination of thevarious devices, substantially as hereinafter more fully speci-Referring to the accompanyin g drawings, wherein I have illustrated oneand the preferred embodiment of my invention, Figure 1 is a plan view ofthe box, showing the door 5 box. Fig. 3 is a diagrammatie representationshowing` the Connections, and Fig. 4 is a diagram of the wheels.

The box A may be of anysuitable or desirable construction, and ispreferably provided with a door B, connected to one side of the box byhinges, which form a medium of Connecting the circuits between theswitch O, located on the cover, and the apparatus located within thebox. Secured in the box is a magneto-generator D, which nay be of anysnitable and preferred construction, although I have shown it asconsisting of a number of curved permanent magnets d d, 0 connected bysteps to pole-pieces d' d', be-

tween which rotates the arnature mounted on the shafi; E, as moreparticularly set forth in my application, Serial No.*339,l19, filedFebruary 4, 1890, and bearing on the end coils of the armatureis aplateor brush e, supported on the frame of the nagnet, but insulatedtherefrom.

Supported in suitable bearings between the limbs of the magneias bybrass or other non magnetic plates D is a shaft F, carrying open. Fig. 2isa longitudinal section of the Serial Not 351,178. (No model.)

a gear-wheel f, gearing with the pinion e' upon the shaft E, and alsomounted on the shaft F is a pinion f', meshing with the gear f mounted.ona stud or bearing secu red to' one of the plates D', and having agearf engaging the pinion f* on the cirouit-breaker shaft.

It is often desirable in devices of this kind to be enabled to sendapredetermined Signal nade up of a certain number of smaller signals orimpulses, so that any particular subscriber or other person may becalled by simply rotating the arnature, the circuits being properlyarranged beforehand. In order that this may be done with accuracy and 65 that the timing of the elements of the signals nay be regular withrespect to one another, I provide a number of circuit-breakers, whichare mounted upon the circuit-breaking shaft G, 'and are rotated throughthe 7o V' mechanism just described whenever the shaft is turned and acurrent generated. These circuit-breaking-wheels may be of any desiredconstruction; but I have shown them as consisting of disks havingnotches cut in their periphery or projections extending therefrom, sothat as they rotate they will present a greater or less surface to abrush or other Connecting device, and the circuit will be closed -to agreater or less extent and a given number of times and in certainrelations at each rotation of the disks. These disks are represented atI'I, and are numbered in the present instance 1, 2,' 3, and 4, it beingunderstood, of course, that there'may be a greater or less number ofcircu it-breakers, all mounted on the same shaft, according to the usesto which the apparatus is to be appliedj A number of brushes H' aremounted on a suitable support, and their free ends are held go adjacentto the circuit breakers' and are adapted to make contact therewith asthey rotate on the shaft.

It is desirable that the circuit-breaking shafi; shall make one completerotation in order that a complete Signal may be sent, and should then bestopped, so that the operator will know when he has completed theSignal.

'In order to do this I provide a suitable stopping device which shallcontrol the rotation Ioo of the shafi: F and be in turn controlled bythe rotation of the circuit-breaking shafi'. While different means maybe used for carrying this out, I have shown the shaft F as provided witha block or disk I, having two notches' on opposite sides. The shaft G isalso provided with a disk J, having a single noteh j in its periphery.Pivoted to the frame-work in some suitable position is an arm K,carrying a projection or stop ?ignormally engaging one of the notches'of the disk I, a spring L norinally holding it inthis lockedposition.The arn K is provided with an extension k carrying a disk or wheel M,which is adapted to fit into the slot j in the periphery of the disk J,and a spring m s-urrounds the eXte-nsion of the arn K a-nd presses thedisk M outward against the stop on'.

In Fig. 2 the nachine is shown in its stationary position, and beforethe shaft can be otated it is evident that some means must be providedfor unlocking the d-evice, and I have shown such means as consisting ofa bush-button LT, projecting through the side br the box and operating abell-.crank lever n, which impinges on the end of the rod, forcing theWheel M out of the notch in the disk J, and thereby also releasing theprojection l from the noteh tin the disk I. The shaft F can then berotated, operating the armature to produce the alternative currents,which are controlled by the circuits and switch hereinafterdescribed, so that the particular signal may be sent over the line. Whenthe circuit-breakers have completed one rot-ation, the Wheel M fallsinto the noteh j of the Wheel 1 J, and the projection 7,; is therebythrown into engagenent with -one of the notches z' of the disk I,.andthe apparatus is locked against further rotation. the purpose .ofallowing the dish or wheel M to yield slightly and to act somewhat as abreak to prevent too quick or sudden stopy page 'of the parts, whichmight injure or 0thi erwise disarrange them.

In order to prevent the shaft F being rotated backw-ard, and therebysending the signal in the reverse order from what was intended, I applya ratchet-wheel O on the shaft F, into which the pawl 0 eugages,allowing free rotation in one direction,but preventing rotation in theopposite direction. Suitably nioun'ted in the box is a polarized magnetP, operating the arnature p, carrying the bellhanmer p', operating the.bells in the usual way. The crank Q for drivi-ng the shaft is preferablyprovided with a sleeve Q', having a groove g engaging a pin g' on theshaft, -and a spring (1 tends to naintain the sleeve in its outermostposition, and when the erank is.

closed cireuit, and then `the shaft w-ill be 1 0-- .tated,and=when thecrank Q is released -i-t' will normally return toitsouter position, asshown. Monnted on the cover of the box I have shown I provide the springm for a switch C, consisting of a switch-atm C',

conneeted to a thumb-nut C and having an index-arm 0 passing over aplate or other indicator C The arm C' is preferably of spring material,having a slight projection on its end, which may be beveled to fit thecups or other con tact-pieces c c' 0 0 0 These pieces are conneetedelectrically witl the different circuit-breakers and with the frame ofthe machine, the conductors 1, 2, 3, and 4 being connected to thebrushes of the respective circuit-breaking wheels, and the conductor 5being connected to the frame of the nachine. The switch-arm is connectedby a conduetor G to the binding-post 7, which may lead to the ground, ifdesired. The bindingpost 8 is eonneeted .to .the 'lineire 9, and thenceby a conductor 10 to the eoils of the bell-magnet, from which -aconductor llleads to the conductor 12, and thence to the brush .e on theend of the armature-shaft. From the binding-post 7 a eo nduetor 13 leadsto a spring 14, normally bearing on `the sleeve Q', and another spring15 bears upon the opposite sideand is connected to, the conductor 1-2.Th'us the norinal eircuit when the machine is -at rest is such that asignal from a distant station may operate the bell P, passing throughthe binding-post S, eonductor 10, bell-magnet conductors ll and 12,through the Springs 14 15, eo nduetor 13, and bindingpost 7 to ground.VV-hen, however, the generator is operated, the circuit between theSprings li and 15 is broken, as before described, and it will then betraced from ground through the binding-post '7, conductor 6, to theswitch-arn C', to one of the contactpoints, as 6 thence by the eonductor1 to the brush, over the corresponding circuit-breakin g w-heel to-theshaft of the same, and through the coils of the .armature oi-it throughthe brush e, through the eonduetors 11 and 1.2, eoiis ofthe magnets,eonductor 10, bindingpost 8, and line 9.

It will be understood that the e-ireuit as last traced will be broken orclosed in accordance with the construction and arrangement of thecircuit-l' reakerWheel included therein. These wheels are shown in one.arrangem-ent in Fig. 4. \Vhile many arrangements can be made, I havefound it especially advantageous, when it is desired to call one of a.number of SlIbSCYbGPg fOP instance,upon the same line, to cause apreliminary Signal to be given, and When the uiachine is so adapted Iprovide each eircuit-breaker with a projection X, which will cause as-ignal ofthe desired length to be given and will warn the hearer that acall is to be sent. This is then followed with the desired number ofprojections Y, arranged in proper groups a proper distance apart toinsure the signal given.

It will be seen from inspection that ,the disk X, Fig. 4, will first'send a prelininary Signal and .then a series of signals, which will beread and understood, as 1 2 '3, and each time this disk is rotated thispredeternined IOO IIC

, tinuous signal Will be sent, the circuit being system of signals willbe sent, provided it is included in the circuit of the switch, and anyone of the predetermined signals arranged on the circuit-breaking-wheelscan be sent by moving the switch C', so as to complete the circuitthrough that particular circuit-wheel. If it is desired to send acontinnous signal without interruption, I have arranged a circuit directfrom the frame of the generator through the conductor 5 and the contactc, so that as long as the arnature is rotated a conclosed. It will thusbe seen that by properly adjusting or constructing the circuit-breakersany number of signals can be sent, and they all being securcd upon thesame shaft they can be arranged so that the intervals between thesignals are even and regular, and the listener can readily deterninewhether his particular call or signal has been made ornot.

WVhile I have th us described and illustrated what I consider thepreferred embodiment of my invention, it is evident that many of thedetails of construction and arrangement of parts and circuits nay bevaried without departing from the general and essential features of theinvention, and I therefore do notdesire to linit myself to the precisemechanisn shown and described.
